Last evening I had over 500 Green Darner Dragonflies "swarming" around me and cruising over my yard, field and the adjacent property. There may have been other species but from what I could tell from the ones that were near me they were all the same. A friend experienced the same thing in Mahoning County at Mill Creek Park. I had this occur about 17 years ago at my prior home in southern Trumbull County. I believe there is a name for this phenomenon but can't recall it. Comments? Also, I had one Nighthawk fly over at dusk - the only one I've seen/heard this year.
